well, eqg has stepped in the right direction with rainbow rocks. by that i mean it didn't feel like another magical mystery cure(meaning they told a two episode story in one episode, making it feel rushed with all the music). the music had a valid point in the story and sunset shimmer became likable and properly reformed (and we now have a reason to hate flash sentry, if you are wondering what that reason is, watch the movie). if they do it right, it could work. they seem to be learning from past episodes and eqg 1. i will wait and see.
the book was decent, the movie didn't follow the main traits in the characters of the book. mockingjay was a step in the right direction (cough revolution cough)
if they do follow any traits from the hunger games, human discord should be the villain.
